Reducing oxygen-transport resistance within a catalyst layer for fuel cells by adopting an intrinsically microporous ionomer.

Herein, a sulfonated ionomer with intrinsic microporosity was designed as a catalyst binder in a low-Pt-loaded fuel cell to construct a good triple-phase boundary, achieving an obvious 57% reduction of local oxygen-transport resistance and a notable 47% increase in peak power density of up to 1233 mW cm.

Pupal Diapause Termination and Transcriptional Response of (Lepidoptera: Saturniidae) Triggered by 20-Hydroxyecdysone.

The pupal diapause of univoltine hampers sericultural and biotechnological applications, which requires a high eclosion incidence after artificial diapause termination to ensure production of enough eggs. The effect of pupal diapause termination using 20-hydroxyecdysone (20E) on the eclosion incidence has not been well-documented in . Here, the dosage of injected 20E was optimized to efficiently terminate pupal diapause of , showing that inappropriate dosage of 20E can cause pupal lethality and a low eclosion incidence.

Genome-Wide Identification of M14 Family Metal Carboxypeptidases in Antheraea pernyi (Lepidoptera: Saturniidae).

The M14 family metal carboxypeptidase genes play an important role in digestion and pathogenic infections in the gut of insects. However, the roles of these genes in Antheraea pernyi (Guérin-Méneville, 1855) remain to be analyzed. In the present study, we cloned a highly expressed M14 metal carboxypeptidase gene (ApMCP1) found in the gut and discovered that it contained a 1,194 bp open reading frame encoding a 397-amino acid protein with a predicted molecular weight of 45 kDa.

A Gut-Specific LITAF-Like Gene in Antheraea pernyi (Lepidoptera: Saturniidae) Involved in the Immune Response to Three Pathogens.

Antheraea pernyi (Guérin-Méneville 1855) is an important resource for silk, food, and biohealth products; however, exogenous pathogens largely affect the commercial application potential of this species. Since the gut is a key organ for the digestion and absorption of nutrients as well as for immune defense, we used comparative transcriptome analysis to screen for a gut-specific molecular tool for further functional research in A. pernyi.

A chromosome-scale genome assembly of Antheraea pernyi (Saturniidae, Lepidoptera).

Antheraea pernyi is a semi-domesticated lepidopteran insect species valuable to the silk industry, human health, and ecological tourism. Owing to its economic influence and developmental properties, it serves as an ideal model for investigating divergence of the Bombycoidea super family. However, studies on the karyotype evolution and functional genomics of A.
